INK-GRINDER-ADJ'USTING ATTACHMENT.

Application filed November 12, 1926. Serial No. 147,879.

My invention relates to adjusting mechanismfor ink grinders, and moreparticularly to an attachment for adjusting roller mills.

Under the present method of adjusting the front roll of an ink grindingmill, each of the ends is moved independentlv from the other, thusconsuming considerable time in making the proper adjustment in order tosecure the required fineness of the product.

The principal object of my invention is to so connect the adjustingmeans that all adjustments may be made from one end of the mill.

A further object is to so place the controls that the operator cansimultaneously reach one with either hand.

These objects, and other advantageous ends which will be describedhereinafter, -I attain in the following manner, reference being whichFigure 1 is a plan view of an ink grinding mill on which my attachmenthas been installed, 1

Figure 2 is a front elevation of the shown in Figure 1,

Figure 3 is a view taken on line 33 of Figure 2, some of the parts beingomitted for the sake of simplicity,

Figure 4 is a fragmentary front view, some of the parts being omittedfor the sake of simplicity,

. Figure 5 is a cross sectional view taken on at line 55 of Figure 4,and

Figure 6 is a cross sectional view taken on line 6--6 of Figure 4,

Figures 3, 4, 5 and 6 are drawn to a larger scale than Figures 1 and 2.

Referring 'to the drawings, 7 indicates the frame of a roller mill, 8 abracket attached to one end of the frame, 9, 10 and 11- the millgrinding rolls which are actuated by means of belts engaging pulleys 12and transmit- 4 tin rotation through the train of gears 13,

an 14 represents the discharge apron. The

above enumerated parts are. the principal elements of a well knownroller type grinding mill and will not be further described as they formno part of my invention.

15 and 15 represent the adjustable bearings in which the front roll ismounted. Engaging the front side of the bearing 15 tlfirou h swivelconnection 14 is a screw 16, t r

ed through a block 17 secured to the hadto the accompanying drawingsframe 7,. and having a helical gear 18 mounted near its center. Thescrew is mounted in a bearing 19 which is secured to the frame of themill in an suitable manner. A screw 20, having a elical gear 18 mountedthereon and which is threaded through a block 17 a secured to the frame7, is bored throughout its length and has a secondary screw 21 rotatablymounted therein with its inner end engaging bearing 15 through swivelconnection 14. An enlarged threaded portion 22, of the screw 21, engagesthreads in a counter-bored portion 23- of the screw 20. The screw 20is-mounted in a bearing 24 secured to the frame of the roller mill inany suitable manner. Immediately below the gears 18 and 18, on' thescrews 16 and 20, is mounted a longitudinal shpft 25 having helicalgears 26 and 26 rig-idly secured thereto and meshing with thegears 18and 18 respectively. The shaft is held against longitudinal movement bycollars 27 and 27" secured on either side of the bearings 19 and 24. Ahand-wheel 28 is secured on one end of the shaft 25 and anotherhand-wheel 29 is secured on the screw 21.

- B turning hand-whell 28, attached to sha 25, the screws 1 6.and 20will be rotated by the action of the helical gears 18 and 26, attachedto the screws and shaft respectively. As the screws are threaded throughthe blocks 7 and 7* attached to the mill frame with the inner end ofscrew 16 engaging roll bearing 15 and the end ofsecondary screw 21engaging roll bearing 15, pressure between the rolls may be increased ordecreased asldesired. When it is discovered that the rolls are notbearing evenly throughout their lengths, adjustment is. 95 made byturning hand-wheel 29 attached to screw 21. The hand-wheels are locatedadjacent one another so that the operator may grasp one in either handand instantly make accurate adjustments.

While I have described my invention as taking a particular form, it willbe understood that the various parts may be changed without departingfrom the spirit thereof, and hence I do not limit myself to the pre- 105cise construction set forth, but consider that I am at liberty to makesuch changes and alterations as fairl come within the scope of theappended c aims.

Having thus described my invention, whet 110v 'I claim as new and desireto secure by Letters Patent is 1. In combination with a color grindinmachine having parallel rolls, one of sai rolls being mounted onadjustable bearings, means at either end of said roll operableresponsive to a sin 1e control for simultaneously moving sai bearings toadjust said roll with respect to the other rolls, and means associatedwith one of said adjustable bearings and passing through said firstmeans thereat adapted to adjust said hearing independently of the otherof said bear- 2. In combination with a color grindin machine havingparallel rolls, one of sai rolls being mounted on adjustable bearings, athreaded member at either end of said roll passing through a stationaryblock of the machine and swiveled to said bearings, a shaft having meansthereon and a control for operatingsaid means to adjust said memberssimultaneously, and threaded means passin through one of said blocks andthe mem r associated therewith for moan-r adjusting only the hearing atsaid end of the machine.

3. In combination with a color grinding machine, parallel rolls, one ofsaid rolls being mounted on adjustable bearin a threaded inner member ateach end 0? said roll passing throu h individual blocks thereat, anouter mem r removably secured to each of said inner members, a gear oneach of said outer members, a shaft having gears thereon, whereby uponthe actuation of a single control, said shaft is adapted to actuate saidears and members, one of said inner mem rs being swiveled to one of saidadjustable bearings, a threaded rod passin through the other innermember and swivele to the other adjustable bearing, said rod beinadapted to adjust said bearing indepen ently of the other bearing, bothsaid bearings being adapted to be adjusted simultaneously and equally bya movement of the shaft.

In testimony whereof I have signed my name to tliisspecification.

GUSTAV A. VASEL.
